Shaffer concluded, “We’re pleased to have closed The Villages Bancorporation, Inc. acquisition on October 1, 2025, which, combined with the closing of our Heartland Bancshares, Inc. acquisition in July of 2025, will position us for even stronger profitability measures and earnings in the periods ahead.”

Acquisitions Update

On July 11, 2025, the Company completed its acquisition of Heartland Bancshares, Inc. (“Heartland”), adding approximately $153.3 million in loans and $705.2 million in deposits, along with four branches in Central Florida. Integration activities, including system conversion, were also completed in the third quarter of 2025.

On October 1, 2025, the Company completed its acquisition of Villages Bancorporation, Inc (“VBI”). This transformative transaction expands the Company’s presence in North Central Florida and into The Villages® community, adding 19 branches and approximately $4 billion in assets. VBI’s future growth potential and low loan-to-deposit ratio provide significant opportunity for expansive growth throughout the Seacoast footprint. Full integration and system conversion activities are expected to be completed in the third quarter of 2026.

Financial Results

Income Statement

• Net income in the third quarter of 2025 was $36.5 million, or $0.42 per diluted share, compared to $42.7 million, or $0.50 per diluted share, in the prior quarter and $30.7 million, or $0.36 per diluted share, in the prior year quarter. Adjusted net income¹ for the third quarter of 2025 was $45.2 million, or $0.52 per diluted share, compared to $44.5 million, or $0.52 per diluted share, for the prior quarter, and $30.5 million, or $0.36 per diluted share, for the prior year quarter.

• Net revenues were $157.3 million in the third quarter of 2025, an increase of $5.9 million, or 4%, compared to the prior quarter, and an increase of $26.9 million, or 21%, compared to the prior year quarter. Adjusted net revenues¹ were $158.6 million in the third quarter of 2025, an increase of $6.8 million, or 4%, compared to the prior quarter, and an increase of $28.1 million, or 22%, compared to the prior year quarter.

• Pre-tax pre-provision earnings¹ were $55.9 million in the third quarter of 2025 and included $10.8 million in merger-related charges. Pre-tax pre-provision earnings¹ in the third quarter of 2025 decreased $4.3 million, or 7%, compared to the second quarter of 2025 and increased $9.8 million, or 21%, compared to the third quarter of 2024. Adjusted pre-tax pre-provision earnings¹ were $67.2 million in the third quarter of 2025, an increase of $4.6 million, or 7%, compared to the second quarter of 2025 and an increase of $20.8 million, or 45%, compared to the third quarter of 2024.

• Net interest income totaled $133.5 million in the third quarter of 2025, an increase of $6.6 million, or 5%, compared to the prior quarter, and an increase of $26.8 million, or 25%, compared to the third quarter of 2024. The increase was largely driven by growing loan and securities balances. Interest income on loans increased by $4.8 million in the third quarter of 2025, reflecting continued strong loan production. Securities income increased $3.5 million, or 11%, with year-to-date purchases at higher yields. Included in loan interest income was accretion on acquired loans of $9.5 million in the third quarter of 2025, $10.6 million in the second quarter of 2025, and $9.2 million in the third quarter of 2024. Interest expense on deposits increased $2.5 million, or 6%, compared to the prior quarter, and decreased $8.8 million, or 17%, compared to the third quarter of 2024. The increase from prior quarter reflects higher balances through both organic growth and from the Heartland acquisition. Interest expense on borrowed money decreased $1.0 million, or 9%, compared to the prior quarter, and increased $3.3 million, or 51%, compared to third quarter of 2024. The decrease from the prior quarter reflects a partial repayment of wholesale borrowings during the quarter and the increase from the prior year quarter is largely due to higher short-term borrowings used to fund strategic purchases of securities in advance of the Heartland and Villages acquisitions.

• Net interest margin decreased one basis point to 3.57% in the third quarter of 2025 compared to 3.58% in the second quarter of 2025. Excluding the effects of accretion on acquired loans, net interest margin expanded three basis points to 3.32% in the third quarter of 2025 compared to 3.29% in the second quarter of 2025. Loan yields were 5.96%, a decrease of two basis points from the prior quarter. Securities yields increased five basis points to 3.92%, compared to 3.87% in the prior quarter. While the cost of deposits increased one basis point from 1.80% in the prior quarter to 1.81% in the third quarter of 2025, the cost of funds declined three basis points to 1.96% quarter over quarter.

• The provision for credit losses was $8.4 million in the third quarter of 2025, largely the result of organic growth in loans. The acquisition of Heartland resulted in a day-one provision of $1.9 million. Allowance coverage of 1.34% remains flat compared to June 30, 2025.

• Noninterest income totaled $23.8 million in the third quarter of 2025, a decrease of $0.7 million, or 3%, compared to the prior quarter, and an increase of $0.1 million, or 1%, compared to the prior year quarter. Results for the third quarter of 2025 included $0.8 million in realized losses on securities. Other changes compared to the second quarter of 2025 included:

• Service charges on deposits totaled $6.2 million, an increase of $0.7 million, or 12% from the prior quarter, and an increase of $0.8 million, or 14%, from the prior year quarter. Our investments in talent and significant market expansion have resulted in continued growth in treasury management services to commercial customers.

• Wealth management income totaled $4.6 million, an increase of $0.4 million, or 9%, from the prior quarter and an increase of $0.7 million, or 19%, from the prior year quarter. Assets under management have grown 24% year over year. The wealth management division delivered record growth, adding $258.1 million in new assets under management in the third quarter of 2025, the highest quarterly result in the division’s history.

• Bank Owned Life Insurance income totaled $3.9 million, an increase of $0.5 million, or 15%, from the prior quarter and an increase of $1.3 million, or 50% from the prior year quarter.

• Other income totaled $6.0 million, a decrease of $1.5 million, or 20%, from the prior quarter and a decrease of $1.9 million, or 24%, from the prior year quarter. The second quarter of 2025 included $3.0 million in tax refunds related to a prior bank acquisition. The resulting comparative decline was partially offset by higher gains on SBA loan sales and higher loan swap fees.

• Noninterest expense was $102.0 million in the third quarter of 2025, an increase of $10.3 million, or 11%, compared to the prior quarter, and an increase of $17.2 million, or 20%, compared to the prior year quarter. Merger-related charges totaled $10.8 million in the third quarter of 2025, compared to $2.4 million in the prior quarter. Results in the third quarter of 2025 included:

• Salaries and wages totaled $46.3 million, an increase of $1.9 million, or 4%, from the prior quarter and an increase of $5.6 million, or 14%, from the prior year quarter.

• Legal and professional fees totaled $1.7 million, a decrease of $0.4 million, or 19%, compared to the prior quarter and a decrease of $1.0 million, or 38%, from the prior year quarter. Changes between quarters are largely associated with the timing of various projects.

• Amortization of intangibles increased $0.9 million with the addition of $20.9 million in core deposit intangible assets from the Heartland acquisition. These assets will be amortized using an accelerated amortization method over approximately 10 years.

• Merger-related costs totaled $10.8 million in the third quarter of 2025 and $2.4 million in the second quarter of 2025.

• Seacoast recorded $10.5 million of income tax expense in the third quarter of 2025, compared to $12.6 million in the second quarter of 2025, and $8.6 million in the third quarter of 2024. Tax benefits related to stock-based compensation were immaterial in each period.

• The efficiency ratio was 60.66% in the third quarter of 2025, compared to 56.95% in the second quarter of 2025 and 59.84% in the prior year quarter.
